Fig. 6

Bifurcation diagram for fixed \(0< c< c_{\mathrm{cusp}}\). The parabola shows the two equilibra near the fold \(F^{-}\) (the third equilibrium branch and second SN are not shown). The a-axis is not shown on scale, as the distance between \(a_{\mathrm {snpo}}\) and \(a_{c}\) should be exponentially small. Keeping that in mind, an incomplete canard explosion is seen as a goes from \(a_{c}\) to \(a_{s}\)
